rpt vs. pnn vs. mtn

Hello Board. I'm new to the Aussie boards and was looking for some value guidance on PNN vs. Redport vs. Marathon. They seem to be comparable in cursory value. Can someone confirm my numbers:

PNN:
Crocker Well - .51% U with 6338 tonnes

RPT:
Lake Maitland - .052% U with 7900 tonnes

MTN:
Mt. Gee - .073% U with with 33,200 tonnes (inferred)

Can anyone elaborate on mgmt and mining type, e.g. in-situ, etc. and mining friendliness of South Australia vs. Western Australia?

I'm open to any other input. Thanks in advance!
